Skillpoints
First of all, play a game and save it, then quit the game. Open the "savegameX_Apartment.dat" file in notepad if the character you want to edit lives in an apartment or savegameX_Penthouse if he lives in a penthouse and so long (X is the saved game you want to edit e.g. savegame3_Apartment.dat check the screenshot to be sure) You can find the file in the "\savegame" folder where the singles game is located. Now search for skillpoints, when you find it change its value to 30 search again and change it to 30. Do that until there is no more skillpoints entries. This is to be improved but for now, it does the job. Now run the game open your saved game and spend your new skillpoints!

Bathroom:
Create separate rooms for needs. Put toilets in every bedroom with dressers. Place the shower and tub in separate rooms with a dresser in each. Also have a washer with a sink and mirror. These rooms do not need to be that Cozy.

Common interests for roommates:
Pick your roommates by what they like to watch on television. can tell if someone really likes a show when they jump out of their seat. This is a group activity. If everyone likes the same thing, it saves a lot of time restoring their fun because everyone can watch the same channel.

Dressers:
Buy four cheap dressers. Put one in each bedroom and one in the shower/bathtub room. You do not need a dresser for the pool or hot tub room. Roommates will switch to their swimsuits automatically.

Fixing a broken romance:
For example, take Josh and Anna. Do not flirt with Anna after you declare your love to her. Instead, just romance her. Just buy her a present and get her Romance past 50% on the blue bar. She will come running to you in her panties the next morning, saying how you are the one. You are now back together. You cannot do any romance moves until you heal her broken heart. Do not waste your time using them on her.

Hot tub:
Get a hot tub as soon as possible. Two roommates can wash in it at the same time. It increases Hygiene to 70 or 80% rather quickly. Roommates put on swim suits so there is no embarrassment. Place the hot tub in a room just slightly larger for privacy and high Cozy. If two roommates are already in the tub, no one will disturb you if the hot tub and lighting are the only fixtures in the room.

Play pen:
When your guest arrives, be in room that is the most Cozy. This room should have a couch, television, twin bed, bowl of fruit, and a door leading into the hot tub room and one into the toilet room. This should be built as close as possible to the front door to your apartment. Otherwise, your visitor may go in a less desirable place in your apartment. This will give you more control over your visitor, with no rejection of action because of Cozy. It will also give you more control over privacy from your roommates (opposite sex only).

Roommate relationships vs. Bar Flies:
It takes more than five time longer to get into a relationship with your roommate than it does with someone you talk to in a bar. After two eight hour trips to the bar you will be French kissing. The reason is that The Bar has a very high Cozy level. Take your roommate(s) to the bar to take advantage of this. Note: You cannot take roommates to the bar in the Story mode. However, when you complete Story mode you will gain control of all three players.

Selecting roommates:
For a roommate with the same gender, it depends on your strategy. If the opposite sex lives with you, it is difficult to be a player if you plan on multiple relationships. Roommates will get jealous. Bar Flies only come over when you invite them. Your roommate is always there. Bar Flies and roommates only get jealous if they see you cheating. Select the opposite sex based on your attraction to them. Choose the two opposite sex that you would hit on last.

Two roommates work:
Note: This trick works best when all are the same gender. One strategy is for two roommates to earn money while one plays and cleans. This works extremely well. Have two roommates work on their careers to make money. The second one cleans house. Finish cleaning the house by noon. Then, go to bar or invite someone over for some fun. Make sure you leave the bar by 15:00 so you get back before your roommates get home. Cook them a meal. When they get home they can get their hunger out of the way. Have your two working roommates talk to each other a great deal. The player/cleaner should just socialize with them a little. On weekends, everyone should go to the bar but try not to spend more than five or six hours there unless you have a lot of money. If you get tired with who works and who plays, switch them.

Washer:
You will need a washer because a clean outfit is required to perform in band with Mike in Story mode.
